TL;DR: An algorithm that has been developed to estimate the residual range of an electric vehicle, i.e., the distance that can be covered with the energy stored inside the battery, with special reference to lead-acid batteries is presented.
Abstract: This paper presents an algorithm that has been developed to estimate the residual range of an electric vehicle, i.e., the distance that can still be covered with the energy stored inside the battery. The algorithm takes into account the complexity of the behavior of electrochemical batteries, with special reference to lead-acid batteries, as well as the main issues related to different driving styles. This paper also discusses some of the experimental results obtained by the use of the algorithm in several urban test trips made using two different types of electric vehicles.

TL;DR: The types of sensors reviewed in this chapter are (1) room-temperature hydrogen leak sensors; (2) thermometers, particularly useful at low temperature; (3) liquid hydrogen volume and mass gauges; and (4) para/ortho hydrogen ratiometers as mentioned in this paper.
Abstract: Four types of hydrogen detectors are used by researchers, engineers, and manufacturers today, and if hydrogen continues to play a role in emerging alternative energy sources, there will be exponential growth in the use and need for more advanced and more robust devices in the future. The types of sensors reviewed in this chapter are (1) room-temperature hydrogen leak sensors; (2) thermometers, particularly useful at low temperature; (3) liquid hydrogen volume and mass gauges; and (4) para/ortho hydrogen ratiometers.

TL;DR: In this paper, the main results of studies that have been carried out, during a period of more than a decade, at University of Pisa in co-operation with other technical Italian institutions, about models of electrochemical batteries suitable for the use of the electrical engineer, in particular for the analysis of electrical systems with batteries.
Abstract: This paper documents the main results of studies that have been carried out, during a period of more than a decade, at University of Pisa in co-operation with other technical Italian institutions, about models of electrochemical batteries suitable for the use of the electrical engineer, in particular for the analysis of electrical systems with batteries. The problem of simulating electrochemical batteries by means of equivalent electric circuits is defined in a general way; then particular attention is then devoted to the problem of modeling of lead-acid batteries. For this kind of battery, a general model structure is defined from which specific models can be inferred, having different degrees of complexity and simulation quality. In particular, the implementation of the third-order model, that shows a good compromise between complexity and precision, is developed in detail. The behavior of the proposed models is compared with results obtained with extensive lab tests on different types of lead-acid batteries.
